Thanks so much for your replies, it means a lot to me!
I am sorry for the lack of details. we are pretty sure it's metastases from gastric cancer that he had before, how does it make a difference?
My dad is too weak to do chemo. because his surgery (through which he lost 3/4 of stomach), he eats small meals and don't have enough nutrition I believe. he's not in a hospital yet (the thinking is that once he's admited to the hostpital, he will not be able to leave again). treatment options are very limited indeed (in my mind, nothing of really hope), the doctors I have talked to in China gave no hope, it is indeed a very desparate situation! I went back to China for 3 weeks after the diagnosis, and cannot handle it watching my dad. I must be a very weak person, but the hopelessness and helplessness saddens me everyday like lead weighs on my body.
He is in Jinhua, a mid size city 4 hours from Shanghai. Next week, we will have him try Iressa, which I managed to get from Taiwan, but I don't really believe it because of the new report of its lack of efficacy. however, this is the only thing left on the table if i cannot find a souce of Tarceva.
